MAP - Turbocharger/Supercharger Inlet Pressure Correlation

The Engine Control Module (ECM) monitors the Manifold Absolute Pressure (MAP) sensor and Turbocharger/Supercharger Inlet Pressure sensor signal. The ECM sets the OBDII code when there is a signal correlation problem between the engine computer and MAP or Turbocharger/Supercharger Inlet Pressure sensor.

Cause:
Faulty MAP or Turbocharger/Supercharger Inlet Pressure sensor
MAP or Turbocharger/Supercharger Inlet Pressure sensor harness is open or shorted
MAP or Turbocharger/Supercharger Inlet Pressure sensor circuit poor electrical connection

Symptoms:
Check engine light
